ELEMENT EHWR12BE
window air conditioner · 12,000 BTU cooling · fits ~600 sq ft
A window AC rated 12,000 BTU — enough cooling for a room of roughly 600 square feet (the 20-BTU-per-square-foot rule).
What actually decides this purchase
We publish 91 units at 12,000 BTU. They run within $22 a year of each other — but they sell for $350 to $1,348, a 3.9× spread. Efficiency is not what decides this purchase at 12,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
At $499 this sits above the 12,000 BTU median of $490 — $9 more for cooling that costs the same to run, since the whole class is within $22 a year of itself. That premium has to buy something you can name: quieter running, a better warranty, a fit your window needs. Worth comparing against the TCL H12W4KW at $350 and the Friedrich CCV12A10A at 32 dBA for $600.

Noise
Not published
The maker publishes no dBA figure we could verify, and noise is not part of the DOE certification. It is the most common complaint about window units, so treat its absence as a real unknown.

Worth keeping in proportion: every unit in the 12,000 BTU class runs within $22 a year of every other. The gap between the cheapest and dearest to buy at this size is 46× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.

Frequently asked questions
Is 12,000 BTU right for my room, or should I size up?
About 600 square feet is the guide figure, and 91 certified units sit on that shelf. The next shelf up is 13,000 BTU (5 units), about 650 sq ft. Below it, 11,000 BTU (4 units) covers about 550 sq ft. Between two shelves, take the smaller one: oversizing is the usual reason a unit cools but leaves the room clammy, which our sizing calculator explains.
Will the ELEMENT EHWR12BE fit my window?
Measure your window opening first — it needs to be at least 19" wide (the cabinet width), and the unit is about 15" tall and 22" deep, roughly 51 lb. Most double-hung windows fit units in this range with the included side panels, but confirm your window's inside width and minimum height.
Sources. Certification and CEER from ENERGY STAR room-AC data and the DOE compliance certification database. Cooling capacity, dimensions and refrigerant are the manufacturer-certified values. Annual running cost, suggested room size and the percentile are computed by Verified HVAC Data from published ratings and EIA U.S. average electricity prices — see our methodology. Refrigerant GWP is the IPCC value. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
